Two separate coherent sources with distance produce identical sound waves of wavelength 2.0 [m] that are in phase. Source 1 is at the (0, 0) and Source 2 is at (6.0 [m], 0). If an observer stands at (6.0 [m], 8.0 [m]) in front of the sources, what will be the path difference and how would the sound waves interfere at that point?
Two radio antennas are 120 m apart on a north-south line, and they radiate in phase at a frequency of 3.4 MHz. All radio measurements are made far from the antennas. If the east-west reference line passes midway between the two antennas, what is the smallest angle from the antennas, measured north of east, at which constructive interference of two radio waves occurs?
